STM32汇编LCD初始化
应用背景
本人原创STM32汇编实现LCD的显示,目前搜遍全球也没有STM32汇编实现LCD显示的代码。 编译器 ARM-NONE-EABI ,是在LINUX下编译的。
代码很复杂不容易看懂,我用了很长时间才写出来,大概有1000行汇编代码,写了半个多月才写出来,真是不容易啊。 程序包括IO设置 时钟初始化,NVIC中断设置,定时器,温度传感器等,红外遥控, 然后在LCD上显示
关键技术
初始化代码

ldr r0, = 0x40021000
ldr r1, = 0x14D83
str r1, [r0]

ldr r2, [r0]
ldr r1, = 0x20000
tst r1, r2 @高速时钟标志位

一、 使用键盘显示接口芯片8279接收按键键值,并在七段数码管上显示出来,通过判断键值进入相应音乐播放处理程序。在音乐播放程序中,使用定时器/计数器8253的计数器2,使其工作在方式¬ ¬ 3―方波发生器,通过查表依次取出乐曲频率值送入计数器作为计数初值,经out2输出方波,驱动扬声器发出不同频率的声音,在每个音阶之间加入相应的延迟时间,即实现了音乐的播放。-First, the use of a keyboard display interface chip receive keys keys 8279, and Seven-Segment LED display, through to determine the corresponding music player keys to enter the treatment program. Procedures in the music player, use the timer/counter 2 counter 8253 to work in the way ? ? 3- square-wave generator, followed by out music through the look-up table values into the counter as a frequency count of the initial value, the output side out2 waves, driven loudspeakers of different frequency sound, in between each scale by adding the appropriate delay time, namely, the realization of the music player.
